| 摘 要： | 文章提出了一种改进的魔方变换,采用了基于素数求余的一一映射作为置乱技术,用一个素数和一个自然数作为密码。算法克服了传统魔方变换易被攻击和当图像比较大的时候耗时多等弱点,使得魔方变换在数字图像加密中的应用得到了推广。图像实验验证了改进的魔方变换算法速度更快,置乱效果更好。

| Abstract: | An advanced magic cube transformation using MOD technology is proposed,which take a prime number and a natural number as password.It conquers the disadvantage of traditional magic cube transformation,such as being attacked easily and wasting time in case of large images.The application of magic cube transformation is extended in digital image encryption.The experiment indicates that the advanced magic cube transformation is faster and more effective than the traditional transformation. |
